There are a growing number of sites where you can play the original Tetris online. This puzzle game is available in so many Internet arcades because the owners of the Tetris copyright continue to license it widely.
Where to Play Tetris Online
"Tetris has been licensed to many of the top video game publishers in the world including Electronic Arts, Nintendo, Capcom, Sega and THQ," says Tetris.com, the official Web site of Tetris Holding, LLC, which owns Tetris and licenses it to other companies through a subsidiary called the Tetris Company LLC. This means there are a number of places you can play the game online, and each site is slightly different from the next.

While FreeTetris.org is free, you must watch an advertisement to play the game. The site also has a number of banner ads, and you are required to sign up for an account in order to play.
The site claims that it's the world's most popular site for the game and offers a free version of classic Tetris. You can choose the difficulty level that you want to play, but it's usually best to begin at one of the easier levels, such as level one or two, and then work your way up to the harder levels, such as level nine or ten. While you're playing, you can pause the game if you get interrupted.
